Basic form

Expressed the ratios of values in the basic form:

0,5 t : 1,2 kg
200 l : 0,15 m³
12 t : 3600 kg
500 kg : 2,5 t
0,9 kg : 500 g
3,6 m : 240 cm
1200 mm : 2,4 m
300 l : 0,3 m³
6 min 30 s : 900 s

Correct answer:

a =  1250:3
b =  4:3
c =  10:3
d =  1:5
e =  9:5
f =  3:2
g =  1:2
h =  1:1
i =  13:30

Step-by-step explanation:

$a=0.5\cdot 1000/1.2\approx 416.6667=1250:3$

$b=200/(0.15\cdot 1000)\approx 1.3333=4:3$

$c=12\cdot 1000/3600\approx 3.3333=10:3$

$d=500/(2.5\cdot 1000)=0.2=1:5$

$e=0.9\cdot 1000/500=1.8=9:5$

$f=3.6\cdot 100/240=1.5=3:2$

$g=1200/1000/2.4=0.5=1:2$

$h=300/(0.3\cdot 1000)=1=1:1$

$i=(6\cdot 60+30)/900\approx 0.4333=13:30$
